Lead

Nov 10, 2002First of all, the ore must be concentrated to separate the lead ore from the zinc ore, for example. It turns out to be possible to do this with flotation. A substance is added that wets the zinc ore, allowing it to sink to the bottom, but does not wet the galena, allowing it to be caught up in a foam that floats on the surface of the water. Get price

Galena

Easily recognized by it good cleavage, high specific gravity, softness, and lead-gray streak, this mineral is the primary ore mineral of lead. It is a very common sulfide that has been worked for its lead content as early as 3000 BC. The name is derived from the Latin galena, a name originally given to lead ore. Get price
